To go from a 73-80 to a 81-87/91 front clip you will need the entire front end including cowl panel, hood hinges, bumper with brackets, radiator, and wiper studs(if that's what they are called). You will also have to mount hood hinges on you cowl, trim the frame horns, and possibly move the front frame mounts about 3/4in for the radiator support to line up. Personally I hate to see another round eye lose its identity to a newer clip, especially a 73-74.
